How Phase modulation and frequency modulation are inseparable?
Phase modulation and frequency modulation are related because changes in the phase of a signal result in corresponding changes in its frequency. When the phase of a signal is modulated, it causes variations in the frequency of the signal as well. Therefore, in practice, it is difficult to separate phase modulation from frequency modulation, especially in communication systems where both aspects are interconnected.
What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
How phase lock loop is used as a universal detector for Amplitude Modulation?
A phase-locked loop (PLL) can be used as a universal detector for Amplitude Modulation (AM) by utilizing its ability to track the phase and frequency of the incoming modulated signal. The PLL locks onto the carrier frequency of the AM signal, allowing it to demodulate the envelope variations caused by the modulation. By comparing the output of the PLL with the original carrier frequency, the modulation information can be extracted as the difference between the two signals. This makes the PLL an effective detector for demodulating AM signals across a wide range of frequencies and modulation depths.
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
In which analog-to-analog modulation methods does the peak amplitude of the carrier signal remain unchanged?
Frequency modulation and Phase modulation
Which cellular system uses the most bandwidth efficient modulation?
I think it is Frequency Modulation with Phase modulation which it the most bandwidth efficient
What are the advantages and disadvantages of RC phase shift oscillator?
Advantages: it improves frequency stability. phase modulation n demodulation is easy as compared to frequency modulation.
Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.

What are examples of analogies?
It is a way to see differentences between items. Like: Cow is to barn as elephant is to zoo.
What are the advantages and disadvantages of phase modulation?
Advantage - 1. Phase modulation & demodulation is easy compared to Frequency modulation. 2. Phase modulator is used in determining velocity of moving target by extracting Doppler information. Doppler information needs stable carrier which is possible in phase modulation but not in frequency modulation. Disadvantage - 1. Phase ambiguity comes if we exceed its modulation index pi radian(180 degree). 2. we need frequency multiplier to increase phase modulation index. Visit my website http://harshit.org
